LOUIS BARE AND HENRY REIGHENBAOH, OF DETROIT, MICHIGAN.

STOVE-PIPE.

SPECIFICATION forming part of Letters Patent No. 324,154, dated August11, 1885. Application filed February 5, 1885. (No model.)

To all whom it may concern.-

Be it known that we, LOUIS PARE and HENRY REIOHENBAOH, of Detroit, inthe county of Wayne and State of Michigan, have invented a new anduseful Improvement in Stove-Pipes, of which the following is aspecifieation.

Our invention relates to an improved depipe, the construction being suchthat the length of the pipe may be increased or diminished, as desired,with ease and facility, and

joint preserved, whereby smoke and other products of combustion areprevented from escaping at said joint.

7 Our invention consists in the novel construction and combination ofparts, hereinafter described and claimed.

In the accompanying drawings, Figure l is an elevation. Fig. 2 is a planview of a ring-j clamp. Fig. Sisalongitudinal section through thecompressible ring, and Fig. 4. is a plan view of said ring.

D designates one of the lengths or sections of an ordinary stove-pipe.The part d at one end-of this pipe flares or tapers outwardly from aboutthe point e to its extremity, as will A designates a section or lengthof pipe, of a diameter somewhat larger than that of section D, so thatit will freely slip over the same, and a space be left between the two.At one endthis section is flared or tapered at A in a manner similar tothe .part (2 of pipe D. At the other end said section A is taperedinwardly or contracted, as seen at a, Fig. 1. This portion (6 isdesigned to fit into the outwardly-flared portion of a pipe, similar tothat, D, above described.

B represents a short tapering ring, made of the same material as thestove-pipe, bent in the form of a frustum of a cone, but not fastenedtogether at the scam I), so that the ring an inwardly-turned flange, F.A slips over the length D, with the flange F toward the larger end (I ofD, and is placed at that point on D where the end of the next length isto come, and the length A is then The ring B slipped over length D, andpressed over ring B until it compresses the flange F tightly aroundlength D, and thus makes a tight joint.

0 represents a broken ring, having at each end an eyed lug, one of whichis screw-threaded.

E represents a't-humb-screw,-which passes through one lug and engageswith the screwthread in the other lug, and by turning said thumb screwthe ends of said ring can be brought together. This ring 0 may be usedto hold the ring B at any desired point on length l), by putting thering 0 in a loose state on ring B, near the bead thereon-that is, at apoint farther down on said ring than the end of length A will come, thenplacing ring B at the desired point on length D, and tightening ringscrew E.

Ourinvention can be used without the ring 0; but this ring will be founduseful to keep the parts together when the pipe is tall en down in thesummer, and may be used at any time.

By placing the ring B at different points on length D the total lengthof the lengths A D can be varied to any desired extent within the limitof the range of motion of ring B on length D. The ring 0 may also, ifdesired, be clamped on length D below the lower end of ring B, and, thusused, serves to prevent the ring B from passing too far down on lengthI).

When it is desired to lengthen or shorten the stove-pipe, in order toaccommodate it to pipe-holes of dilferent heights, it is only necessaryto loosen the ring 0, and withdraw the ringB from pipe A suliiciently toallow the sections A andD to be contracted or extended, as it may bedesired to shorten or lengthen the pipe. The ring B is then forced intosection A a suflicient distance to firmly clamp section D, and the ring0 tightened up by means of thumb-screw 1t.

YVhat we claim as our invention, and desire to secure by Letters Patent,is

1. The combination, with a length of stovepipe, of a pipe-section oflarger diameterfitting thereon, and having one end contracted,

U by means of the thumbas shown, and a tapering compressible ringfitting over the smaller section of pipe and entering the largersection, substantially as described.

2. The combination,with a length of stovepipe, 1), and a section, A, oflarger diameter fitting thereon and having a contracted end, a, of acompressible ring, B, formed of a tapering piece of pipe loosely bentinto a frustum of a cone, and having at its base an inwardlyextendingflange, F, substantially as described.

.3. The combination,with a length of stovepipe, D, and a section, A, ofgreater diameter fitting thereon and having a contracted end portion, a,of a compressible ring, B, formed 10 of a tapering piece of pipe looselybent into a frustnm of a cone, and the clamp having therein screw E;substantially as described.
